If you are using cloudflare to hide your servers IP address, then you need to ensure you don’t send email from that server. Reasons:

  • Creating a SPF record to avoid email going to spam will require you to specify the servers IP address – fail!
  • Sending an email will reveal your IP address in the email header.

The solution is to use a third party SMTP mailing service.
